[yt-users] PerspectiveCamera question

I'd like to try using the PerspectiveCamera instead of the normal orthographic Camera. My script renders fine with Camera(), but I thought that I should be able to just change Camera() to PerspectiveCamera() and it should render with the perspective. Instead, I get an empty rendering -- is there something else one needs to do to use the PerspectiveCamera rather than just changing the class name but otherwise keeping the argument list the same?
